1. A child sleds down a snow-covered hill with a uniform acceleration.
The slope of the hill is 38.5 m long. If the child starts at rest and
reaches the bottom of the hill in 5.5s, what is the child’s final speed?

i think the answer is a, hope this is right, that would be my best guess.

think its the third option

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
